Hey @dustinmiller1337,

thanks for your PR!
Before we can merge this, we need some test-coverage for suse. I created a docker-image that you can use to test your PR: https://hub.docker.com/repository/docker/rndmh3ro/docker-opensuse_tumbleweed-ansible

We have three different testing methods:

• local testing with test-kitchen and docker. For this, see the .kitchen.yml: https://github.com/dev-sec/ansible-os-hardening/blob/master/.kitchen.yml
• local testing with vagrant: https://github.com/dev-sec/ansible-os-hardening/blob/master/.kitchen.vagrant.yml (you can use a vagrantbox from the internet)
• testing with travis: https://github.com/dev-sec/ansible-os-hardening/blob/master/.travis.yml

I'd like to have at least two of these three testing methods integrated in this PR. If you have any questions, feel free to ask!
